Corespun yarn with double cores makes denim fabric less deformed
　　Corespun yarn is a kind of composite fancy yarn, of which, cotton covered spandex yarn corespun yarn is widely used, usually used in casual clothing, denim clothing and knitted swimwear.
　　In use, the core yarn of cotton covered spandex yarn will produce the phenomenon of core yarn exposed. Spandex yarn has the disadvantages of low strength, high breakage rate, compressed feeling and poor comfort. In order to adapt to the elastic fabric to the high-end development of demand, Zhejiang spinning enterprises have developed a double-core core yarn, micro-elastic and rigid core yarn two new core yarn, popular with the post-processing enterprises.
　　With T400 composite silk and spandex two core yarn production of double core silk core yarn, can make the denim fabric with elasticity, not easy to deformation, improve the strength of the yarn and wear resistance, and wear without binding and pressure, comfort significantly improved; with micro-elastic wire and metal wire for the core yarn and the core yarn produced with cotton wrapped polyester low elastic wire, not only make the fabric has a certain elasticity and conformability, and overcome the original The core yarn made of metal wire has the functions of radiation resistance and high temperature resistance, which can be used as special working yarn.
　　With the improvement of covering technology, the production of cored yarn has developed to the direction of high-count yarn, which can be used for high-grade garment fabric, changing the pattern of cored yarn which only produces medium and coarse count yarn.
　　Bamboo yarn is more fashionable for apparel
　　Bamboo yarn is a popular fancy yarn, which can be used in knitted fabrics and denim fabrics to make the surface of the fabric show irregular bamboo style, and adapt to the requirements of fashion and novelty of clothing. With the popularity of bamboo knot style in denim garments, the market demand for bamboo knot yarn has increased greatly.
　　Previously, denim fabric mostly with airflow yarn, but airflow spinning to spinning bamboo yarn is difficult, high transformation costs, so Zhejiang spinning enterprises through the appropriate transformation of equipment, by changing the front and middle and back roller rotation speed, to achieve in the ring spinning machine can produce bamboo yarn. In addition, different forms of bamboo knot styles such as knots in knots and waves can be produced to meet the needs of clothing designers.
　　According to the survey, currently, 20%-30% of spinning enterprises are equipped with intelligent bamboo yarn devices. Bamboo yarn is widely used in local color yarn, color spinning yarn, semi-worsted and wool spinning enterprises, and has become a key product for Zhejiang spinning enterprises to adjust their product structure.
　　High added value of segmental color yarn
　　Segment color yarn developed on the basis of bamboo yarn is a novel composite fancy yarn. In addition to rich layers and three-dimensional sense, it also has rich color changes, which is more in line with the fashion trend and can be widely used in the production of garment fabrics. Unlike bamboo yarn, segmental yarn is produced by feeding two roving yarns from the back roller and the middle roller into the drawing area of the spinning machine, and then producing gradation effect with different speed change of the roller.
　　At present, the segment color yarn is not only produced in this color yarn enterprise, but also expanded to color spinning enterprise, semi-worsted enterprise and wool spinning enterprise. Especially in the semi-worsted and woolen spinning enterprises, with multi-color wool fiber, silk fiber and combed cotton and other raw materials, the production of segment color yarn, product grade, high value-added, with the yarn woven into sweaters by domestic and foreign customers praise.
　　According to preliminary statistics, more than 30 spinning enterprises in Zhejiang have installed more than 300 new colorful yarn devices. Since the price of segment color yarn can be 5,000 yuan/ton~10,000 yuan/ton higher than that of conventional yarn, enterprises can obtain better economic benefits, and the number of enterprises producing segment color yarn is increasing further.
　　Color dot yarn and snow yarn have different styles
　　Color dot yarn and snowflake yarn are also two novel fancy yarns developed and produced by Zhejiang spinning enterprises in recent years. The colored dot yarn is made by hand or machine by mixing colored fiber particles in the spinning process, so that the yarn produced has colored dots on it. The fabric woven with colored dot yarn has colorful dots evenly distributed on the fabric surface, which is beautiful and especially suitable for making women's knitted and woven garments.
　　Because of the addition of short fiber particles, the yarn is generally spun coarser, between 100tex~250tex (4~10 counts). It is used in more combed tweed, such as the tweed in the fire moss (steel tweed), etc., are woven with color dot yarn. Also useful polyester staple fiber rolled into particles, mixed in the cotton yarn, woven into cloth with room temperature dyeing, so that the surface of the fabric appears brilliant and colorful dots, forming a unique a style.
　　Snowflake yarn is made of millimeter-like short fibers (also called short pile) fed in spinning into yarn, and woven into fabric to show a small star pattern one by one on the fabric surface, which is a different style of yarn from colorful dot yarn. With the offcuts produced by their own factories can be used as raw materials, so it can reduce the cost of spinning for enterprises, but also make the yarn present a different style from the conventional yarn. At present, the number of enterprises producing snowflake yarn is also gradually increasing.
　　Color spinning yarn has a large profit margin
　　Color spinning yarn is the leading product in fancy yarn. Zhejiang is one of the important bases for producing color spun yarn in China. In recent years, Zhejiang Province spinning enterprises to produce fancy yarn technology applied to the production of color spinning yarn, so that the appearance of color spinning yarn form structure has changed significantly.
　　The enterprises have developed more than 10 kinds of novel color spinning yarns, such as color spun bamboo yarn, segment color yarn, color spun dot yarn, color spun rondelle yarn, color spun chiffon yarn and color spun AB yarn produced with the technology of cyclo-spinning, and imitation twist color yarn produced with the technology of coarse yarn cyclo-spinning. Not only expand the color spinning yarn varieties, and greatly enhance the quality of color spinning yarn grade, so that the added value of the product significantly increased, the profit space increased, the production enterprises continue to increase.
　　In addition, because Zhejiang Jiaxing area has Puyuan and Honghe two of the country's largest sweater market, promote the production of semi-worsted yarn and research and development. Semi-worsted yarn is a new variety of color spinning yarn, because its raw materials to the main wool fiber, so its product grade is higher than the cotton-based color spinning yarn, the profit space is greater than the conventional yarn, in recent years has also been rapid development.
　　According to preliminary statistics, at present, Zhejiang has more than 70 spinning enterprises, nearly more than 2 million spindle capacity in the production of various types of color spinning yarn and semi-worsted yarn. Among them, there are more than 40 enterprises in the cotton textile industry, more than 1.6 million spindles (excluding Bailong Huafu at home and abroad to build factories to produce color spun yarn) yarn capacity; more than 30 semi-worsted enterprises, 400,000 spindles yarn capacity in the production of various semi-worsted yarn, accounting for 20% of the total number of spindles in the province, color spun yarn and semi-worsted yarn has become the two characteristic products of Zhejiang spinning industry.
